The Phillies (14-14) will wrap up their three-game series with the Washington Nationals (17-13) on Sunday afternoon.
First pitch is scheduled for 3:05 p.m. (CSN) at Citizens Bank Park.
Here are five things you need to know:
1. Scratch that
Phillies ace Cole Hamels was expected to start on Sunday but the left-hander has been been pushed back to Tuesday against the Toronto Blue Jays.
Hamels has been battling the flu and was sent home shortly before the Phils' game against the Nationals on Saturday. Hamels should be eager to get back out on the mound after a rough outing in a 6-1 loss to the Mets on Tuesday. He allowed six runs on eight hits and five walks over 4 2/3 innings in that start, his second of the season.
So with Hamels sidelined for Sunday's series finale, Roberto Hernandez (1-1, 5.74 ERA) will take his spot in the rotation.
Hernandez was skipped in the rotation last week and pitched one-third of an inning of relief in Tuesday's loss to the Mets. In his last start, Hernandez allowed four runs and seven hits over six innings in a 5-4 loss to the Arizona Diamondbacks on April 25.
As a member of the Cleveland Indians, Hernandez faced the Nationals twice. He went 1-1 with a 2.40 ERA in those starts, which included complete-game three-hitter on June 12, 2010.
2. Gio the great
Former Phillies farmhand Gio Gonzalez (3-1, 3.25 ERA) will get the ball for Washington.
The left-hander has had plenty of success against the Phils, going 5-2 with a 2.66 ERA in eight career starts. To make matter worse, he's given up three earned runs or fewer in each of his six outings at Citizens Bank Park.
Gonzalez is off to a strong start in 2014. He overcame shoulder soreness in his previous outing to surrender just three runs and strike out a season-best nine batters through six innings of the Nats' 4-3 win over the Houston Astros on Tuesday.
Gonzalez has allowed two runs or fewer four times this season and the Nationals have won five of his six starts.
3. The Big Piece
Ryan Howard set the tone for the Phillies in their 7-2 win over the Nationals on Saturday. The first baseman crushed a three-run homer in the first inning and has now gone yard 38 times against Washington in his career.
Howard has been strong at the plate over the last week and a half. He's registered at least one hit in each of his 12 games and is on pace to hit more than 35 homers this season. He's also on pace to drive in more than 100 runs.
But Howard has struggled mightily in his career against Gonzalez. He's 0 for 8 with four strikeouts versus the Nationals' lefty.
4. Right back at it again
Veteran reliever Mike Adams struggled in the Phillies' series-opening loss to the Nationals.
With the Phils up by one run in the eighth, Adams failed to record a single batter. All three Nationals he faced in the inning got hits and eventually scored on hits against Jake Diekman. Adams took the loss and saw his ERA balloon to 8.31.
But that didn't stop manager Ryne Sandberg from going right back to Adams on Saturday. Adams struck out two batters in a perfect eighth before turning it over to Antonio Bastardo, who struck out the side in the ninth.
5. This and that
• Marlon Byrd is 13 for 29 with two homers and 10 RBIs in his last seven games.
• Two of the Nationals' four hits on Saturday were home runs. Adam LaRoche and Zach Walters both went yard.
• After going 1 for 4 with a homer against the Nats on Saturday, Cody Asche is hitting .400 (14 for 23) with five RBIs against Washington in his career.
• Prior to Saturday, the Nats had won eight of 10 meetings with the Phils.
• Jimmy Rollins went 4 for 5 with two runs scored on Saturday. He had gone hitless in 11 at-bats prior to that performance.
